The LiMAx test is an innovative enzymatic liver function test. C-methacetin, a selective metabolite of the liver specific cytochrome P450 1A2 is administered intravenously. Via the bloodstream the drug is transported to the liver and immediately metabolized to paracetamol and ultimately to CO2 (Fig. 1), which is in turn transported via the bloodstream to the lung and exhaled. Cytochrome P450 1A2 is evenly distributed over all the cells of a liver acinus, and is in contrast t… WebThe aims of this study were to establish a novel variant of the methacetin-based breath test LiMAx that allows to estimate and to eliminate the confounding effect of systemic 13 CO …
